Exercise 2.1

Answer 1

★Solving equations ★

2x /3= 18

We will do this problem by Transposing terms.

A term in multiplication when transposed become division & vice versa.

2x=18 ✖ 3

2x =54

x = 27

…………………………………

1.6=y/1.5

1.6*1.5 =y

y = 2.4

………………………………………………………

7x -9 = 16

7x =25

x=25/7

…………………………………………………

Answer 2

1)
2x/3=18
2x=18×3
x=54/2
x=27

2)
1.6=y/1.5
1.6×1.5=y
y=2.4

3)
7x-9=16
7x=16+9
7x=25
x=25/7
x=3.5714285714
